Output Diagnostic Test Mode (DTM) (function 03), conducting

NOTE:

The output DTM can only be carried out when the selector lever is in "P" position, the engine is running, and the vehicle is standing still.
The output DTM is discontinued when the engine is started.
The function of the solenoid valves 1 -N88-, 2 -N89- and 3 -N90- and the shift lock solenoid -N1 10- are checked audibly during the output DTM. During the audible check the surrounding noises should be limited, since the clicking noises are very quiet.
Solenoid valves 4 -N91-, 5 -N92-, 6 -A/93- and 7 -A/94- are triggered by the output DTM. A direct functional check of these components is not possible. However, electrical malfunctions, which occur during this triggering, are eventually stored in the DTC memory through the OBD program.
During the output DTM the individual controls are triggered until the => button is pressed.
Only a complete final control diagnosis is possible after the ignition is switched on. To repeat, the ignition must be switched off and switched on again.
